Anyone know if I will see any real benefit changing my MY06 WRX prodrive backbox for a full Spec-C MY06 TB exhaust system which includes the racing cats and back box?
I have the chance of one for around £250 but dont know what, apart from a possible 10-15BHP increase, do for the car without a remap.

I dont fancy paying out for a remap as well so would it be worth doing?

Turbo back would include the downpipe which would not fit your car. Due to the twin scroll setup on the Spec C the mouth on the downpipe is a different shape.

Thanks for the help on this, i am a novice on these things and only bought my first scooby 2 weeks ago and found info on the 06 hawkeyes hard to come by.
Thanks again
